ABSTRACT:
A media library system has a plurality of independently-operated library arrays disposed in a side-by-side relationship along a first direction. Each of the library arrays has a media drive and a plurality of media storage receptacles arranged in a second direction that is transverse to the first direction. A separate media transport apparatus in each of the library arrays has a moveable media holder for moving media along the second direction between the storage receptacles in the library arrays and the media drives, respectively, in the independently-operated library arrays. A media exchanging and input common apparatus has a media carrier disposed for movement adjacent a common end of all of the independently-operated library arrays along the first direction. The media carrier has a media-transfer stop location at each of the library arrays at the common end of each of the library arrays. Each of the media transport apparatus moves the respective media holders to be aligned with the media carrier while the media carrier is disposed in the media-transfer stop location. The media carrier has a media input-output location that is disposed in a predetermined misalignment with all of the separate media transport apparatus. Access to the media carrier from outside the library apparatus is limited by mechanical interlocks while the media carrier is in its media input-output stop location.
